The VentureStar was a proposed SSTO spaceplane. A single-stage-to-orbit ( SSTO) vehicle reaches orbit from the surface of a body using only propellants and fluids and without expending tanks, engines, or other major hardware. The term usually, but not exclusively, refers to reusable vehicles. [1] To date, no Earth-launched SSTO launch vehicles ...
Stellar mass is a phrase that is used by astronomers to describe the mass of a star. It is usually enumerated in terms of the Sun 's mass as a proportion of a solar mass ( M☉ ). Hence, the bright star Sirius has around 2.02 M☉. [1] A star's mass will vary over its lifetime as mass is lost with the stellar wind or ejected via pulsational ...
Mass number [ edit] The mass number, also called the nucleon number, is the number of protons and neutrons in an atomic nucleus. The mass number is unique for each isotope of an element and is written either after the element name or as a superscript to the left of an element's symbol. For example, carbon-12 ( 12 C) has 6 protons and 6 neutrons.
SATA. SATA ( Serial AT Attachment) [a] [2] is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives. Serial ATA succeeded the earlier Parallel ATA (PATA) standard to become the predominant interface for storage devices.
October 15, 1966. The Massachusetts State House, also known as the Massachusetts Statehouse or the New State House, is the state capitol and seat of government for the Commonwealth of Massachusetts, located in the Beacon Hill [3] [4] neighborhood of Boston. The building houses the Massachusetts General Court ( state legislature) and the offices ...
Massachusetts is the sixth-smallest state by land area. With over seven million residents as of 2020, [note 1] it is the most populous state in New England, the 16th-most-populous in the country, and the third-most densely populated, after New Jersey and Rhode Island.
Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. [1] The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg).
Climate change-related exceptional marine heatwaves in the Mediterranean Sea during 2015–2019 resulted in widespread mass sealife die-offs in five consecutive years. Repeated marine heatwaves in the Northest Pacific led to dramatic changes in animal abundances, predator-prey relationships, and energy flux throughout the ecosystem. [5]
